Problem is in 10 slabs I have had 5 rounds that were poorly formed and disfigured, they wouldn't go in the gun. About another 5 that had a lump in the side that I had to thumb into the gun, and 2 of these that have just popped when firing!

I know they are an economy shell but when they work they work well.

Is there another Winchester 1oz shell that compares in performance but with better components?
